All supporting material layered pavement is in place, use the water from the pool evenly sprinkle the top material way, thrown into the estimates intent manganese sand filter (inclusive of light material and should be scraped less than the specified minimum size of fine particles ), and then washed. Manganese sand filter breakage and wear and should not be greater than 3%. By supporting the filter wall and manganese sand filter material layers top high draw horizontal lines, as pavement highly symbolic. Manganese sand filter is usually uniform density 3.2g/cm3 to 3.6g/cm3 scale inside. Manganese sand filter should be free of visible soil, shale and foreign debris, clay content should not exceed 2.5%. Manganese sand filter commonly used standard :0.25-0 .5 mm 0.5-0.8mm 0.8-2.0mm 1.0-2.0mm 2.0-4.0mm 4.0-8.0mm 8.0-16mm special standards can be processed separately according to user needs. Manganese sand filter: is the use of domestic quality, grain density, mechanical strength, chemical activity, not broken, do not dissolve in water, natural manganese ore. After washing polishing cleaning, drying, magnetic separation, screening, dust and other technology into the sand. Manganese sand then processed by a certain gradation blending. It has a water filter ideal grading scale, it has the largest volume in the unit specific surface area, the strongest interception capacity of the largest and smallest catalytic oxidation backwash churn. Manganese sand filter appearance of rough brown or light gray, commonly used in drinking water in addition to iron, manganese filters, water treatment effect is very good. (Note: MnO2 ≥ 35% either in addition to iron, but also manganese, MnO2 ≤ 30%) can only be used for groundwater in addition to iron) manganese sand filter mainly used to reduce the water content of iron and manganese, ferromanganese total, according to China drinking water standard gauge its iron content ≤ 0.3 mg / L, Mn ≤ 0.1 mg / L, iron manganese content is too high for a long time drinking water will seriously affect their health. I plant many times to major domestic pure water, mineral water, beverage plants, breweries, water plant several together to do according to customer requirements of various levels, a variety of manganese sand filter, please call to discuss
